Texture streches on the edge of extruded plane
If I were you I would just add a UV Seam to both edge rings of the sides, by clicking on the edge ring with Alt + LMB and then adding a seam with U &gt; Mark Seam, and then unwrapping with U &gt; UV-Unwrap. That way you can split the sides from the UV-map which is probably whats causing the weird overlapping!
